Water Quality

The Cottagers’ Association members have authorized the executive committee to conduct more advanced water analysis starting in 2010. Samples will be taken from both the river and lake and analyzed according to a more complete set of parameters including:

The chart below represents the results from water quality tests between 1998 and 2015 based on the Lake Partner Program results. As results are made available, they are posted on the charts below. Note where there is a reading of 0 in either chart below it is an indication of no data available due to an issue on the Lake Partners website.

A high total phosphorous reading (i.e. <20-25) coupled with a low clarity reading indicates high algae content which is bad for fish as algae depletes oxygen needed for fish. On the other hand, too high a clarity reading tends to indicate low nutrients, and an acidic condition detrimental to fish habitat.
